Samenvatting
The paper presents a view of how considerations of transport and traffic have played a role in policy formulation, alongside other (demographic, socioeconomic, environmental, etc.) considerations and objectives. After elaborating the general characteristics of and the preference for urban concentration, the paper concludes with a global preview of developments beyond the planning period (i.e.the 21st century ). An urban development along interurban transportation axes seems a highly relevant possibility.
